We are here to help you get answers to your questions about OneSimCard phones and services.
Can I disable per MB/Pay-As-You-Go data usage for DataMax SIM cards
Yes you can. On your online account, in the "My SIM cards" menu, you will see a section labeled "Select SIM Card." In that section there is a line labeled "Use w/o Plan." If you do not want to use data on a per MB/Pay-As-You-Go basis, and only consume data with a data plan, set this to "Off."Does calling a mobile phone cost more than calling a landline?
It does not cost more to dial an international mobile number using OneSimCard service on traditional cellular connections. You will receive the same very low per minute rate whether calling to a mobile phone or to a land line.Â
Â
For OneSim VoIP, the cost of calling Mobile numbers is typically higher than calling landlines, but this method is still less than traditional voice calls in most countries..
You can find all rates listed on our Rates & Coverage page.

How do I check my OneSimCard balance?
For Universal, Expedition, & eSIM World ONLY: Just dial 099 "Send" from your OneSimCard phone and in few minutes the balance will be displayed on the screen of your phone. Customers with iPhones can use OneSimCard Assist app to check balances and many other things.
You can always check your current balance by logging onto your OneSimCard account at www.onesimcard.com.
Do international cell phones purchased from OneSimCard come with a warranty?
Unless otherwise noted, all phones sold on OneSimCard.com come with our standard 90-day replacement warranty. This warranty covers any mechanical defects, but does not include damage due to Acts of God, neglect, water damage, or other intentional or unintentional abuses of the phone. OneSimCard does offer extended warranties available for purchase.
Where can I find the settings required to be entered into the OneSim VoIP app?
Once you create the OneSim VoIP account, you will be emailed settings and instructions. You can also see the settings in the My SIM Cards menu of your online account.Is there a monthly or 30-day credit card spending limit for OneSimCard service?
Yes. To reduce fraud and to protect you from over-spending, there is 30-day credit card spending limit set for each individual account. You will only be able to charge up to a certain amount during any 30-day period. You can see your current limit by logging in to your OneSimCard account and going to the Purchase History menu. There, you will find a Credit Card Authorization form available for download. If you would like to increase your monthly credit card spending limit, please download the Authorization form and submit it back to OneSimCard as instructed on the form.
We strongly suggest that you set your monthly credit card limit before going overseas as dealing with the form on the road can be much more difficult.Â
Do I need to have Data Roaming turned on for eSIM to work?
Yes. Data Roaming should be enabled on your phone for eSIM for data to work. Calls and texts on eSIM World should work with or without it.
